The multi-cleaning filament tool is recommended for daily maintenance of OTE hearing devices. The filament line end of the multi-tool quickly clears wax related blockage commonly found inside micro poly-tubes and sound domes. The magnetic tip of the tool provides secure insertion and removal of hearing device batteries. No more dropped batteries on the floor! Use the soft brush tip to clean exterior surfaces and sound ports of your hearing device. The kit includes six filament multi-tools in a convenient storage case and instruction manual.
